CAR-COU PLING.

SPECIFICATION formingpart of Letters Patent No. 440,134, dated November 11, 1890.

Application filed April 22,1890. Serial No. 348,961- (No model.)

To aZZ whom it may concern.-

Be it known that I, JOHN CALVIN BURNS, a citizen of the United States, residing at Hughes Springs, in the county of Cass and State of Texas, have invented certain new and useful Improvements in Oar-Couplers; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereof. Fig. 3 is a plan view of the same, partly broken away; and Fig. at is a detail view of the operating-lever.

The same designations indicate corresponding parts in the views.

The draw-head A, having a recess A and a sloping projection C from the base thereof, is provided with an elastic cover D, to which an arm E E is screwed. The projection C engages one end of the bent link H, which is disengaged therefrom by the vertical elevation of the arm E, on which it rests. This elevation is caused by the crank-lever F, centrally bent upon itself to form a lifting-arm F, by which the cover D is raised. This manipulation is effected by actuating connecting-rod G, either from the top or side of the car. The counterpart draw-head is similarly constructed. Pins are entirely dispensed with. The cover D may be hinged, if preferred.

Having thus fully described my improvements, what I claim is As an improved article of manufacture, a car-coupler whose draw -head is provided with an elastic cover having a link-lifting arm secured thereto, a lever for oscillating said cover, performing the duplex function of disengaging the link and permitting its egress, a sloping projection from the base of said draw-head engaging the link on contact, and the bent link, herein shown and described.

In testimony whereof I afiix my signature in presence of two witnesses.

JOHN CALVIN BURNS.
